Abstract
A patient positioning table has a base part with a longitudinal axis and a support plate for positioning a patient. The support plate can be displaced in the direction of the longitudinal axis of the base part relative to the base part. The support plate is provided with a device that can interact with an acceptance device of the base part such that the support plate can be rotated relative to the base part after acceptance of the device of the support plate into the acceptance device of the base part of the support plate. The patient positioning table is suitable for a computed tomography apparatus.
Claims22
A patient positioning table comprising:
- a base having a longitudinal axis and a vertical axis;
- a support plate disposed on said base, and being configured to receive a patient thereon, said support plate being displaceable relative to said base along said longitudinal axis;
- an acceptance device on said base;
- and
- a plate device attached to said support plate that projects into said acceptance device and structurally interacts with said acceptance device that allows rotation of said support plate relative to said base axis and that arrests said rotation and holds said plate device and said support plate only at a plurality of rotational positions relative to said base.
A computed tomography apparatus comprising:
- a gantry having a central opening therein;
- a rotatable frame disposed for rotation in said gantry;
- an x-ray source and an x-ray detector mounted on said rotatable frame for rotation with said rotatable frame around said opening;
- and
- a patient positioning table for moving a patient into and out of said opening, said patient positioning table comprising a base having a longitudinal axis, a support plate disposed on said base and being configured to receive a patient thereon, said support plate being displaceable relative to said base along said longitudinal axis, an acceptance device on said base, and a plate device attached to said support plate that projects into said acceptance device and interacts with said acceptance device to allow rotation of said support plate relative to said base axis and that arrests said rotation and holds said plate device and said support plate only at a plurality of rotational positions relative to said base.
